This table 2 is adjusted in its front-rear and right- left positions by handles 6, 7 and a rotating grind-stone 5 is adjusted in its vertical position by a handle 8. Then, by operating this grinding machine, the work 4 is ground with the rotating grindstone 5. During this grinding process, a cooling liquid is injected from a cooling liquid injection nozzle 11 uniformly on the contact area between the rotating grindstone 5 and the work 4, controlling the temperature rise of the rotating grindstone 5. The cooling liquid is scattered in the closed chamber, however it is collected in a catch pan and injected again from the cooling liquid injection nozzle 11 by the cooling liquid circulating mechanism; thus the cooling liquid is repeatedly used. In this way, a new ceramics test specimen difficult to process can be ground with high precision.

Abstract: PROBLEM TO BE SOLVED: To obtain a sheet-like polarizing element with a light scattering function which has high light utilization efficiency and is free from the thermal deterioration of polarization characteristics by the absorption heat generation of a light source by converting the randomly polarized light to the polarized light of only the one direction without light absorption in the polarizing element which takes only the polarized light of the one direction out of the randomly polarized light without utilizing light absorption dichromaticity as with conventional polarizing plates and a liquid crystal display element formed by using the same. SOLUTION: Multilayered dielectric films 40 alternately laminated with high-refractive index layers/low-refractive index layers are arranged between the slopes of the respective prisms in such a manner that these films attain nearly a Brewster angle with an incident light source in the prisms which are alternately superposed on each other and are continuously worked to a right-angled triangular shape and vary in refractive indices. The randomly polarized light which is made incident is separated to P polarized light and S polarized light and, thereafter, only the S polarized light of the reflected light is converted to the P polarized light via a halfwave plate 50 arranged on the respective prism faces parallel with the incident light.  The transmitted P polarized light and the converted P polarized light and respectively taken out and, further, the converted P polarized light is scattered, by which the taking out of the linearly polarized light polarized to the one direction without having the directivity out of the randomly polarized light without the light loss is made possible.

Title: Extracting device for center line of graphic
Inventor: MASUYA YOSHINORI
IPC: G06T5/30
Filed: 1988-10-07
Abstract: PURPOSE:To increase the picture processing speed by limiting the picture processing area to a graphic that is actually processed. CONSTITUTION:The start point (reticle) of a center line is set on an edge line of a graphic 10, and the center line searching vectors are extended in all directions around the start point. Thus the tracking direction candidate points are searched. Then the intersecting points P and Q are obtained between a straight line passing through the tracking candidate points and vertical to the searching vectors and the graphic edge line. The first tracking direction point K is detected out of the tracking direction candidate points based on the distance between those intersecting points and the tracking direction candidate points. The second and subsequent tracking direction candidate points are searched by limiting the the searching directions to a fixed range based on each preceding tracking direction. In the same way, the second and subsequent tracking direction points are detected. Thereafter the tracking direction points are continuously updated until no tracking direction candidate point is searched any more, and the center line of the graphic is extracted. As a result, a picture process area is always limited to a graphic that is actually processed and therefore the picture processing speed is increased.
